Salivary amylase is a protein secreted by the epithelial cells of the salivary glands to aid in carbohydrate digestion. Order the steps below for the generation of amylase in their correct order. The amylase polypeptide folds into a protein inside the ER lumen and is packaged in a vesicle destined for the Golgi

A release factor binds a stop codon on the amylase mRNA

Vesicles containing amylase leave the Golgi and fuse with plasma membrane to secrete protein from the cell

The growing polypeptide chain continues to insert itself inside the lumen of the ER

Ribosome is fully assembled and translation elongation proceeds

The tRNA charged with Met amino acid recognizes the AUG on the amylase mRNA bound to small ribosomal subunit

RNA polymerase binds to the amylase gene promoter

A mature mRNA is exported out of the nucleus

RNA elongation proceeds until RNA polymerase falls off the DNA

A poly A tail is added to the 3' of pre-mRNA

Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring? o a. populations will go extinct since the warblers will stop migrating to breeding grounds. b. populations will be unaffected since most species can quickly adapt to effects of climate change. c. populations will increase since warmer temperatures are generally beneficial to survival, d. populations will decline since individuals will be less likely to successfully reproduce, reset next

Looking at this image, what relationship can be drawn from it? the lower the degree of latitude, the lower the degree of temperature there is no relationship between latitude and temperature the higher the degree of latitude, the higher the degree of temperature the lower the degree of latitude, the higher the degree of temperature

Acertain species of fish can have either long or short fins. the allele for long fins is dominant over the allele for short fins. a heterozygous, long-finned fish is crossed with a homozygous, short-finned fish. of the offspring, will have long fins and be , and will have short fins and be .
